Please post your tvfool report using your exact address (which will not show) so that we can see what your signals look like using this:

Next, I'm going to try the new one at the same exact location as the one that's working and see what happens.

good idea
Does the flickering happen on all channels, or just certain channels?
What antenna are using and where is it located, inside or outside?
Are you using a preamp? If yes, what model?
Are there any trees or buildings in the signal path?
Where are you located?

Should I assume it's the tuner on the TV?

If it still does it, I can narrow it down to the TV.

It's too early to tell.

If it is the TV, could a replacement of the same model fix the issue? Or, will it likely have the same issue?

The performance of tuners can vary from brand to brand, and even from model to model within the same brand. But, the performance of tuners for the same model should be similar. If not, the tuner is defective.
When I test tuners I use a splitter to feed both tuners at the same time to get a real-time comparison. The strength of OTA signals is constantly changing, so removing the coax from one TV and connecting it to the other isn't the most accurate way, but it is good enough for your present test.
To make an accurate comparison I insert a variable attenuator before the splitter and make the signal progressively weaker to see which TV drops out the signal last:
Code:
TV 1
/
antenna > coax > variable attenuator > splitter >

TV 2
